  • d8a8559cd   writeback: get rid of generic_sync_sb_inodes() export ... Browse Code »

    This adds two new exported functions:

    - writeback_inodes_sb(), which only attempts to writeback dirty inodes on
    this super_block, for WB_SYNC_NONE writeout.
    - sync_inodes_sb(), which writes out all dirty inodes on this super_block
    and also waits for the IO to complete.

  • 36ec4ab8c   Staging: pohmelfs: fix kconfig dependencies ... Browse Code »

    pohmelfs wants to use CONNECTOR, so it selects CONNECTOR,
    but when CONFIG_NET is not enabled, connector.c will not build,
    since select does not follow the dependency chain.
    Selecting NET is not a good idea, since that would build lots
    of code that someone seemingly didn't want to build/store
    and kconfig shouldn't do that behind someone's back.

    pohmelfs should depend on NET since it uses network interfaces.

    pohmelfs also uses CRYTPO and selects 2 cipher symbols, but
    it should also select the top-level CRYPTO symbol since
    kconfig dependency chains are not followed.
    (found by inspection)
    This allows the POHMELFS_CRYPTO option to depend only on
    POHMELFS and makes the kconfig menu align properly.

    Also fix minor typos & line lengths in kconfig help text.
    Drop CONFIG_* in kconfig symbols in Kconfig file.

  • c09ee9d20   Staging: pohmelfs: transaction layer. ... Browse Code »

    This patch implements transaction processing helpers
    used to allocate/free/insert/remove and other operations
    with the transctions.

    Each transction is an object, which may embed multiple commands
    completed atomically. When server fails the whole transaction will be
    replied against it (or different server) later. This approach allows to
    maintain high data integrity and do not desynchronize filesystem state
    in case of network or server failures.

  • d35eef1b4   Staging: pohmelfs: network operations. ... Browse Code »

    This is a main network processing patch. It includes
    both low-level socket machinery, zero-copy sending helpers,
    receiving and parsing callbacks and mainly logical
    commands handlers.

    POHMELFS uses async network approach, when every command
    can be separated from its answer and received after some
    time after the request during which another lots of commands
    can be injected into the network and replies to them received.

    With read operation balancing between multiple hosts it is possible
    that operations will arrive out of order and this is handled
    by the transaction mechanism described partially here.

    Having a transaction to guard the set of logically compound operations
    allows to send data without thinking about its status and using
    zero-copy sending mechanism, since transaction will receive explicit
    acks from the servers when they are completed.

    This patch also contains header with network srtuctures, commands
    and short comments on how they are used.

  • ac7036c13   Staging: pohmelfs: distributed locking and cache coherency protocol. ... Browse Code »

    POHMELFS utilizes writeback cache, which is built on top of MO(E)SI-like
    coherency protocol. This patch includes its implementation and cache
    object processing helpers (like allocation and completion callbacks).

    POHMELFS uses scalable cached read/write locking. No additional requests
    are performed if lock is granted to the filesystem. The same protocol
    is used by the server to on-demand flushing of the client's cache (for
    example when server wants to update local data).

  • b3f08cad3   Staging: pohmelfs: inode operations. ... Browse Code »

    This is the main patch which implements inode operations
    (like reading and writing) and superblock processing
    (filesystem registration, initial autoconfiguration
    with the server like permissions, size of the exported
    dir, amount of the objects created and so on).

    POHMELFS relies on system's writeback cache mechanism
    shown here, as long as cache coherency protocol described
    later.
